The world's greatest detective appears in Victorian London to assist Mike in solving a mystery. True to his legendary reputation, Holmes applies sharp reasoning and keen observation to help Mike navigate the dangers of 19th-century England.

Despite his apparent destruction, Zoda survived. Rather than face Mike directly, he created three clones (Zoda-X, Zoda-Y, and Zoda-Z) of himself to continue his legacy and sent each one to a different era in history to hunt down the Tetrads.
